Yeah the 9:1 CR kind of suprised me. That seems very odd they would build a motor with HIGHER than normal compression when 90 octane would be used. If anything they should have kept the stock CR or even gone lower, not higher.

^ not if they were never intending on running high boost. Higher compression makes for better off boost power, better spool, and makes a lot more power on low boost than low compression motors. Wonder why Honda's make so much power..... its not all in the head.

Yes it does, but going from 8:8 to 9:1 will not make any noteable difference what so ever and he just gave us a dyno on 90 octane and not one with high boost! Nor did he mention anything about running high boost.

It does? Maybe if this was on a stock 2.0, then yeah, but this is a stroker motor, yet the turbo still doesn't spool quickly. 4800 for peak torque at such low boost is not good for a stroker, and the peak torque is also weak for a stroker. i would be quite disappointed in this if I had spent money on a stroker and 50-trim. Then again, it is an RNR kit. As for only having 90oct, wouldn't the obvious choice be to then get alky? $500 for alky to gain tons more torque and HP or $3k for a stroker motor to get much less? YMTC...
So, you could remove the turbo kit, go back to the stock 2.0, remove the AEM EMS, add alky, and you would get:
- More torque
- Similar max whp
- 1000rpm earlier spool
- 0 credit card balance
- Higher reliability
- Less hassle
Nice!

Actually, YOU'RE not too bright and I don't think YOU'RE getting the picture.
Comparing two different dynos is stupid. I could drive to CFT right now and make 340hp on their mustang dyno, but if I drive to Japtrix, I'll only make 305hp on their dyno and that would be the same fuel and the same altitude. That's a 10% difference. Then if I go to Machines Gone Wild, I'll make 335 on their DynoJet, and if I go to Twilight Performance, I'll make 360.
You have no idea what, if any correction factor was used on his dyno sheets, and probably not on yours either. Plus there is a huge difference between 90 octane and 93 octane fuel, even at the same boost, there is no way you can run even close to the same timing. And there is no way you made 400hp on a stock turbo at 21psi (which is what EvO6-RS2 was running).
So yeah, who's not getting the picture?
